How to disconnect wireless router?

CONTINUAL DISCONNECTION OF WIRELESS CONNECTION
There are a few things that can cause you to lose wireless connection with your wireless router.
1. Weak signal strength, check the signal strength on your wireless card. If it is weak move the wireless router away from walls and if possible locate the wireless router higher up.
2. Have you secured your wireless router from people near your from unauthorized access? ie. change the default password, setup encryption use WPA2 or WPA, change the default SSID, and turn off SSID broadcast, and for added protection, enable MAC address filtering which allows only the MAC address/es of your wireless card/s to connect to your wireless router.
3. You could be getting interference from electrical sources such as air conditioners, arid welders, washing machines etc. If so the power supply to the wireless routers and computers etc should be connected to a surge protection power board, better still connect your computer equipment to an UPS (Uninterrupted Power Supply)
4. Check the channels of the wireless routers and access points in your area and change the broadcast channel on your wireless router to an unused channel or one that is currently used but has the weakest signal strength. This will minimize interference with your wireless router from other wireless routers and access points in your area.
